i oredi test on the shop and it "really" heat rejection...... but after install to my car and the heat from sun, it turn to non heat rejection...how come like that!!
is it the tinted just good for test and not for really heat from sun!!!
this 1 am not sure la, there are so many way they do the business. do u still have the warranty card stated which model u have? if do bring to another similar shop to verify la. but i dont think yur is 90% heat rejection.
but sometimes if car park under the normal hot sun for hours using v-kool also hot la, but driving 0ut with air cond are differenet story.
